`rc` collects exit status all the way down but is not used at all? If `code`
comparison at exit is intended then there exists some path that leaves it in
garbage value, say when `ldap_whoami` or `ldap_cancel` fails.

Prevent forks of release branches from triggering CI/CD when pushed. All work in forks should be done in a non-release branch

Tighten validity checks

Regression from fix for ITS#7403

This needs to be confirmed:
Location based atomics do not imply a full fence of the same level. So
to get the code in dispose() read the actual data, it seems we need to
initiate a fence.

It is used internally to identify pinned operations and should not be
encountered over the wire.

If we're idle, there might be objects pending cleanup for the last two
epochs. Unless another thread comes in and checks into a new epoch or we
shut down, they will linger forever.

If one of the objects was a connection, it wouldn't get closed and be
stuck in CLOSE_WAIT state, potentially refusing another ligitimate
connection if its socket address were to match the one we're yet to
close.
